only flaw I noticed was to do with the writing the girl (I assume it was a girl – the face is never shown) was doing. in the beginning, there was a scritchy sound as of a lead pencil writing, later on after the colour comes on there was no sound at all, but it looks like it was a ball-point pen that was used in both cases.

Disturbing is right, gave me the creeps anyway. Very atmospheric & clever in as much as it only hinted & left your imagination to do the rest.

I once spent 14mths living in a Queen Anne Georgian house near Mullingar. It had only been updated just enough to be barely comfortable, most of the original fittings were still intact. The place gave me the creeps, especially in the middle of the night when annoyingly, I used to have to go for a piss across a big landing. The film gave me the same feeling as I used to get on those nights. Congrats to all involved.
